INC OF NEVJ YORK, N. Y., A CORPORATION OF NEW YORK MOTHPROOFING CABINET Application filed July 17, 1931. Serial No. 551,448.

This invention is a moth proofing cabinet adapted to be installed in a clothes closet and constructed to contain a moth proofing agent preferably of a toxic, volatile nature, which is adapted to exit from the cabinet in the form of gas or vapor, permeate the closet and not only repel moth, but actually kill those present.

The device of this invention is particularly adapted to be permanently installed in the closet and may be made in the form which permits it to be built into dwellings during their course of fabrication, so as to come flush with the closet wall, although in another form of the invention, the cabinet may be placed on any closet wall, so as to project outwardly from the surface of the wall.

The cabinet of this invention embodies, generally speaking, a receptacle adapted to contain moth balls of any appropriate form, but by preference the moth repellant and toxic is in solid pellet form and differs from the ordinary moth balls in that the pellets are of toxic character and not merely moth repellant. The casing has a front plate which is provided with openings for the escape of the fumes or vapor and these front so that the condition of the charge may beobserved from time to time. The casing embodies further features of novelty which will be hereinafter more fully described.

The accompanying drawing illustrates different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a front perspective View show-' ing the invention in one form.

Figure 2 is a central vertical section through the structure of Figure 1.

Figure 3 is a fragmentary perspective looking fromthe back of a modified form of the invention.

The cabinet shown in Figure l is of the type which I preferably fasten directly to a wall surface. It comprises a front section 1 69 and a back section 2, these sections being flanged in opposite directions to telescope into one another. In other words, the front section comprises a front plate 3 having rearwardly extending flanges 4, while the back section 2 comprises a back plate 5 having forwardly extending flanges 6. The back plate 5 is perforated at suitable points, for example, as indicated at 7 and through these perforations screws may be passed to aflix 70 the back section firmly to the wall and the" front section is thereupon exteriorly telescoped over the back section. The flanges 4 have punched in projections 8, while the flanges 6 have reglsterlng perforations, so

that after the parts have been telescoped as" stated, the projections 8 enter these perforations and hold the parts in assembled relation. The parts of the casing are made from sheet metal and the flanges are thus more or 89 less resilient to permit the parts to be sprung together as stated.

hen it is desired to remove the front section, this may be accomplished by exerting 'suflicie'nt pull on the front section to dislodge 5 the projections 8 from the perforations in the flanges 6.

The front plate 3 is provided with a series of cut outs 9, the margins of which are embossed or curved togive finished edges. so

These cut outs 9 may in practice be of any desired shape and by preference, I preferably group them in different series to form a neat andaesthetic design or series of designs, so

that the device will be pleasing to the appearance and will be ornamental rather than otherwise. Back of these openings and in facial engagement with the interior face of the front plate 3 is positioned a sheet of suitable porous material 10. Different sub; 10o

stances may be used in the fabrication of this sheet, but I find it convenient to use blotting paper. The sheet preferably covers the entire inner face of the plate 3 and may be 5 either adhesively secured to the late or may be clamped in position between t e plate and the flanges 6.

The purpose of the sheet is to hold back :or slow up fuming or evaporation of the ma- 10 terial adapted to be contained in the casing and to also preclude any dust or particles of the material from falling through the openings during the charging of the device with the moth repellant and toxic. The repellent and toxic emplo ed is preferably of solid ellet form as in icated at 11, and, as shown in Figure 1, the pellets are adapted to be deposited into the casing through one or more .holes 12 provided in the front plate. The

to blottingpa or 10 is cut away at these holes to permit t e pellets to be inserted and another portion of the blotting papers is cut away as indicated at 14, so that one may look through the openings 9 and through the hole 55 14 in the sheet 10 to determine whether or not there are suflicient pellets within the easin some cases, one or more of the openings 9 are by virtue of the particular design emplo ed sufiiciently large to permit of the intr notion of the pellets and in such case, it

' is entirely practical to cut a hole in the sheet 10 adjacent one or more such openings and near the top of the casing for the introduction of the pellets. In such a case, the special 'o'penings 12 for this purpose may be The structure shownin Figure 3 differs from the structure of Figures 1 and 2, in

that the device of Figure 3 is adapted to be set iiitothe wall. To give a finished edge,

the'front plate is extended as shown at 15 the flange 4 instead ofbeing made inwith the front plate forms part of '45 Tanan'gle section, the other flange 16 of which "is spotwelded to the back of the front plate. The structures otherwise are identical, With the structure of Fig. 3, the holes corresponding to the holes 7 may be employed in the "back Section to make the attaching means invisible when the parts are assembled, but we find it more desirable to perforate the extended'portion of the front plate to receive screws 17 as shown in Fig. 3 for attaching the device in osition.

ally, the fumes therefrom will permeate the closet continuously and maintain therein an atmosphere into which mot-h will neither enter nor in which moth or larvae can survive. The use of the blotting paper or other ii porous sheet 10 is found to hold back or slow up the evaporation of the moth proofing agent, so as to prolong the operation and to feed the fumes into the closet in a more uniform manner. In other words, the use of this sheet forms the easing into a substantially closed chamber through which the fumes, in the main, must filter into the closet and does not therefore permit the constant, rapid attack of atmospheric air upon the V0 atile pellets which would cause them to rapidly break down.

The structure which has been described is economical to manufacture, easily installed, can be charged periodically by a housewife without any particular knowledge or skill and is thoroughly efiicient for its intended purposes. The two forms which have been shown and described are those which I prefer to employ, but are disclosed for the purpose of illustration only. The invention is to be understood as fully commensurate with the ap ended claims.

ny suitable moth repellant or toxic, or a combination thereof may be used in the cabinet of this invention, but I preferably use pellets embodying paradichlorobenzene and cedar oil. 7

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. 'A mothproofing cabinet embodying a pair of sheet metal telescoping sections collectively forming a. chamber adapted to con tain a moth'proofing agent, said telescoping sections having male and female members adapted to be sprung into engagement to hold them in assembled relation against inadvertent displacement from one another, one of said sections being provided in the face thereof with openings, and a porous filtering medium covering said openings, said filtering medium being cut away in juxtaposition with one of said openings to permit the introduction of a moth proofing agent into the casing.

2. A moth proofing cabinet'embodying a pair of sheet metal telescoping sections collectively forming a chamber adapted to contain a moth proofing agent, said telescoping sections having male and female members adapted to be sprung into engagement to hold them in assembled relation against inadvertent displacement from one another, one of said sections being provided in the face thereof with openings, and a porous filtering medium covering said openings, said filtering medium being cut away in juxtaposition with one of said openings to permit the introduction of a moth proofing agent into the casing, and said filtering medium being also cut away near the bottom of the casing and in juxtaposition with at least one of said openings, so that the amount of moth proofing agent within the receptacle may be observed.

3. A moth proofing cabinet embodying a hollow casing provided in one face thereof with openings, and a porous filtering medium covering said openings, said filtering medium being cut away in juxtaposition with one of said openings to permit the introduction of a moth proofing agent into the cass- 4.
